                Using 64-bit atomic operations on 32-bit x86 with gcc versions older
                than 4.7 and compatible compilers can result in generation of incorrect
                code. This problem is fixed in <a href="https://github.com/boostorg/atomic/commit/a67cc1b055cf09f371e2eca544884634a1ccc886">this</a>
